In New York Low Sand-cherry has most often been found on open sand areas on dunes along Lake Ontario, and occasionally also found in other open sandy habitats (New York Natural Heritage Program 2011). Sand dunes and sandy soil, especially on the shores of the Great Lakes (Gleason and Cronquist 1991). Active sand dunes, especially along the shores of the Great Lakes; in both wet and dry habitats; open sandy, gravelly, or bouldery beaches of lakes and shores of rivers, in crevices of rock faces and ridges; on sand dunes, flats and barrens, also in sedge mats of bog and fens and in wet depressions between dunes (Soper 1982). Dunes and sands or calcareous rocky shores (Fernald 1970).
Great lake sand dunes.
Distinguishing characteristics: low or trailing shrub; stem erect; erect or strongly ascending or sometimes decumbent branches and branchlets; diffusely branched; leaves narrowly oblanceolate, tapering gradually from near or above the middle to the narrowly cuneate base and slender petiole (1-1.5cm long) to the acuminate apex; blade mostly 4-7.5cm long and 0.6-1.5cm broad, coriaceous, dark green and lustrous above, slightly paler but scarcely glaucous beneath, appressed-serrate above the middle; deciduous stipules 1.2-1.5cm long, thread-like, fimbriate or setose; purple to blackish cherry, 1.0-1.5cm in diameter; stone subglobose, apiculate at tip, rounded at base, 6-8mm broad. Best life stage for ID: in leaf with flowers or fruit. Characteristics needed to ID: stems, leaves, fruit.
Prunus pumila var. cuneata has leaves elliptic to oblong or narrowly obovate, blunt or merely short-acute, whitish beneath; stone acute, rounded at base, 5-6mm broad. Prunus pumila var. depressa has trailing branches, forming mats up to 2m across; leaves spatulate-oblanceolate to spatulate-obovate, pale beneath; stone ellipsoid, acute at both ends, 4.5-6mm broad.
